RSBRS02AI is a compact size, cost effective single-mode Bluetooth low energy module based on RF-star 256 KB flash SoC RS02A1-A chip with super low power consumption (BLE TX with LDO: 10.6 mA @ 0 dBm, BLE RX with LDO: 8.8 mA @ 1.0 Mbps), good noise reduction, better sensitivity, robust transmission distance, and high reliability.
RF-star's RSBRS02AI is a compact size, cost-effective single-mode Bluetooth low energy module based on RF-star 256 KB flash SoC RS02A1-A chip with super low power consumption (BLE TX with LDO: 10.6 mA @ 0 dBm, BLE RX with LDO: 8.8 mA @ 1.0 Mbps), good noise reduction, better sensitivity, robust transmission distance, and high reliability. The module integrates a 16 MHz crystal, an RF matching filter, a power filter, and an IPEX connector to configure the high-performance antenna. It supports BLE stack v4.2 and is preprogrammed with an easy-to-integrate serial interface communication protocol. RSBRS02AI is pin-to-pin compatible with RSBRS02AA.
